WHAT ARE THE PROPERTIES OF AGGREGATES FOR …

For the preparation of economical concrete mix on should use largest coarse aggregates feasible for the structure. IS-456 suggests following recommendation to decide the maximum size of coarse aggregate to be used in P.C.C & R.C.C mix. Maximum size of aggregate should be less than. One-fourth of the minimum dimension of the concrete member.

Coarse Aggregate Properties

Coarse Aggregate Properties. The properties of the coarse aggregate used in a concrete mixture affects the modulus for a few reasons. One property is the modulus of elasticity of the coarse aggregate. A higher aggregate modulus will result in a concrete having a higher modulus. As expected, a lightweight aggregate will have a lower modulus than the mortar paste. Conversely, a strong aggregate ...
